A Claims; (cl. 290-55) My invention relates to wind-driven power plants of my wind electric plant arts thereof positioned tor normal Fig. 2 is a top view; Fig. 3 is disposed in non-operating position. and

Fig. 4 is currents 01' air. Anelectri ventional d'csisn, 18 mounted, with the axis of rotation oi its revolving parts t ,ontheupperendotthetower'r manner as to permit erator G about a vertical axis.

" formed on the cal generator G, which may he oi con horinonthreaded apertured portions oi the frame I into an internally screw-threaded recess in the lower portion of the saddle 5 and secured therein by appropriate means such as the set-screw 1a.

l and parts carried thereby.

A short distance above itslower end, the pipe 7 in a snide bearing in mounted in thereto for conversion by the'generator G into electrical power.

The propeller driven generator described above is provided with a'tail for normally maint the propeller in facing relation to the wind. A. constructed of sheet material; the longitudinal the vane l4 and boom 3 wili ala position xtendin to apply rotative mechanical power iromthelcn- 0o from which the wind is coming. Means is provided for swinging the generator G relative to the boom B between relative positions wherein the axis of ,';rotation of the. shaft I3 01 the generator! is respectively parallel and substantially at right angles to the boom B. A channel-shaped element is formed intoa U-shaped member l9 and the free ends thereor are secured to the inner end portions or the respective: boom members 15 and ii. in such manner that the U-shaped member I9 is disposed in a vertical plane at an obtuse angle to the boom B as best shown in Figs. 2 and 3. The U- shaped member l9 constitutes a shifting or operating arm by means of which the angle between the boom B and the rotational axis of the generator shaft l3 may be varied to swing the generator relative to the boomB. The member I! because of its U-shape, is enabled to straddle the generator G instead of strikim the same. Brace bars Isa extend between and are secured a. respective ends to the operating arm I! and the boom 13, as shown, so as to insure the rigid relation the operating arm I9 to the boom B. One end'oi an elongated flexible element such as the chain 20 is connected to the operating arm I9.

at the middle of the curved portion thereof. The chain 20 is trained over a sheave 2| revolubly mounted, on the side of the generator by means of a bracket 22 and a pivot screw 22a as shown. From the sheave II the chain 20 extends through an aperture 5c in the saddle member 6 and then through a guide tube 23 which is disp sed within the pipe I, is secured at its upper end in the ap rture 5c and depends at its lower end below spring 2! is connected at one generator G and the (not shown) the lower end .of the pipe I. The chain 20 is of suflicientlength to depend a substantial distance below the lower end of. the guide ,tube 23 so as to be readily accessible to an operator of the plant. It should be apparent that pulling on the depending lower portion of the chain It will swin the operating arm i9 and the sheave 2| toward each other to change the relation between the boom B from that shown in Fig. 3 to that shown in Figs. 1 and 2 and thus bring-the plant into operation. To change the relation between the generator G and the boom B to that shown in Fig. 3 and thus shut down the plant when the chain 20 is released or in case of the chain breaking, a helical tension end to the upper member" of the boom B and at the other end to a spring anchoring element 25 on the frame of the generator G as Anchoring means such as a common cleat or other suitable means, should be provided .on the lower part of the tower '1 portion of the chain 20 may be anchored thereon when itis desired to hold the chain 20 in downwardly pulled position to keep the plant in operation.

iii

A stop membe lab is provided on the generator G, as shown, to engage the operating arm I! as the boom 3 reaches a position approximately at right angles to the axis of the generator shaft ii. men the boom B is swung into operative relation with the generator the bracket 22 serves as a stop member and is engaged by the operating am Is.

It is apparent that .I have invented novel,

elongated members and so that the depending lower a,oss,o1a

emola m a direction opposite to the direction carrying out the objects above set forth and in the novel parts and combinations of parts disclosed and defined in the appended claims.

What is claimed is:

1. In a wind operated power producing plant,

a body, a propeller mounted on said body for rotation about a substantially horizontal axis, a support for said body, said body being mounted on said support for rotation with respect the'reto about a vertical axis, a vane-supporting boom comprising a pair of spaced elongated members disposed substantially horizontally and one above the other. a vane disposed in a vertical plane and secured to the outer portion of said boom, the inner ends of the upper and'lower elongated members of said boom being respectively pivotally attached to the upper and lower portions of, said body to provide for swinging oi said boom in a. horizontal plane relative to said body, a generally U-shaped member secured at its respective free ends to the inner portions of the respective disposed at an angle thereto to form an operating arm straddling said bow, yieldable means urging said boom toward a position at one angle relative to the rotational axis ofsaid propeller and actuating means connected to the medial portion of said U-shaped member adapted for operation to actuate said U- shaped member to swing said boom into a second angular relation with said rotational axis.

2. In a wind operated electric generating plant, a supporting structure, a propeller driven generator mounted on said support ment relative thereto in a substantially horizon tal plane, a vane adapted to parallel to the wind direction, forming the inner end of said vane and positioned one above the other, said members being pivotally connected to said generator to provide for turning of said generator relative to said vane, means for turning said generator between positions thereoiextending substantially parallel and nor mal to said vane, and a U-shaped element secured at its inner end to the respective ones of said members and positioned to engage said generator when the same is in one or said positions.

3. The structure defined in claim .2 and astop mounted on said generator in position to engage said U-shaped element when said generator is in the other of said positions. Y v

4. The structure defined in claim 2 and a flexible elongated control element connected at one end to said U-shaped element, and guide means on said generator over which said flexible, element passes and from which said flexible element extends downwardly whereby tension on the lower portion of said flexible element will pull said generator toward said one of said positions.

5. The ent means. connected between points respectively on said vane and said generator for urging said generator toward one of said positions.
